New driver for menf21bmc.
Convert k10temp, smsc47b397, da9052, da9055 to new hwmon API. Register ntc_thermistor driver with thermal subsystem. Add support for F15h M60h to k10temp driver. Add driver for MEN14F021P00 BMC HWMON driver; this required a merge with tag mfd-hwmon-leds-watchdog-v3.18. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJUNZQwAAoJEMsfJm/On5mBxZEQAIf555P39+4fkRIrf3oYUuC2 q1tXNP0u8Z74eDFfwYYobt+NCJG5KW3H3kFaO5WCTjySfVwjUin9Fc6DkLl2m3U+ 4FfH/2rO1y1upVRQemLAhe7BAYJAzABuNFWbLqqbGbZytyf5sHzhP52vjJ5VNmvr 5zcn/sGJdB5M9tj3isvfrac0itNu+D7K3qxknk4wI5gb6YzKg+uovXscPVx4Xa7w eHKXJWITtBAZdD5bDV5YAzlTR15ASG3h+yyV7G5rKgslYyCMuRfIDm8Rl5zzHUmq DjLwwib469NMii6CjdC7kEpYOgJ2ZxK/2XQ5IAeGax8GLdIHB6lhp3GrXIzzRwiW 5mtsMdRB7y41p050rIXN7AIXGVqSvtZtKf0r8w1p5YElat/wtX9gv0lGTgOq4sSa 0SOE7E6W0cfe75dYgJP/6HIkuZZ7PweBelQYDfWrN00u/rdIcwC2nRnW/nDbctkr TmQLiS0ql2mXPWXD+Lk9v3bUALuYOPuQpX2aARj7en7jeBagP6KX0d70GaoAEzGk Gw6z4X4gI3TasuIck4LZx3kaiijEnDOgnIaEQah4b3k7ABEiuOYVBBpnWvqECaSD p9/lwFAs2POCsYSuADiclzxH6FLCMRJLE2V7dgMun9uK60o+0pGUqBL1PG/5/w+r jGdB/75PCOEn3Y/VlfZg =vI5p -----END PGP SIGNATURE----- Merge tag 'hwmon-for-linus-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging Pull hwmon updates from Guenter Roeck: - new driver for menf21bmc. - convert k10temp, smsc47b397, da9052, da9055 to new hwmon API. - register ntc_thermistor driver with thermal subsystem. - add support for F15h M60h to k10temp driver. - add driver for MEN14F021P00 BMC HWMON driver; this required a merge with tag mfd-hwmon-leds-watchdog-v3.18 * tag 'hwmon-for-linus-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/groeck/linux-staging: hwmon: (ab8500) Call kernel_power_off instead of pm_power_off hwmon: (menf21bmc) Introduce MEN14F021P00 BMC HWMON driver leds: leds-menf21bmc: Introduce MEN 14F021P00 BMC LED driver watchdog: menf21bmc_wdt: Introduce MEN 14F021P00 BMC Watchdog driver mfd: menf21bmc: Introduce MEN 14F021P00 BMC MFD Core driver hwmon: (ntc_thermistor) Add ntc thermistor to thermal subsystem as a sensor. hwmon: (smsc47b397) Convert to devm_hwmon_device_register_with_groups MAINTAINERS: add entry for the PWM fan driver hwmon: (k10temp) Convert to devm_hwmon_device_register_with_groups hwmon: (k10temp) Add support for F15h M60h hwmon: (da9052) Convert to devm_hwmon_device_register_with_groups hwmon: (da9055) Convert to devm_hwmon_device_register_with_groups hwmon: (ads1015) Use of_property_read_u32 at appropriate places

=============================

Description
|
||||
-----------
|
||||
|
||||
The menf21bmc is a Board Management Controller (BMC) which provides an I2C
|
||||
interface to the host to access the features implemented in the BMC.
|
||||
|
||||
This driver gives access to the voltage monitoring feature of the main
|
||||
voltages of the board.
|
||||
The voltage sensors are connected to the ADC inputs of the BMC which is
|
||||
a PIC16F917 Mikrocontroller.
|
||||
|
||||
Usage Notes
|
||||
-----------
|
||||
|
||||
This driver is part of the MFD driver named "menf21bmc" and does
|
||||
not auto-detect devices.
|
||||
You will have to instantiate the MFD driver explicitly.
|
||||
Please see Documentation/i2c/instantiating-devices for
|
||||
details.
|
||||
|
||||
Sysfs entries
|
||||
-------------
|
||||
|
||||
The following attributes are supported. All attributes are read only
|
||||
The Limits are read once by the driver.

||||

||||

|
||||

|
||||
